Case Study: Crawl Space Encapsulation to Eliminate Moisture and Odor in Kitchener

Location: Kitchener, Ontario
Client: The McLaren Family
Issue: Persistent dampness and odor in crawl space causing indoor air quality concerns
Service: Full crawl space encapsulation with vapor barrier and drainage system

The Challenge

The McLaren family had recently moved into a century home in Kitchener’s downtown core. Shortly after settling in, they noticed a persistent musty odor on the main floor. Further investigation revealed that the crawl space below their home was damp, unsealed, and had no moisture control system in place. There were signs of standing water after rainfall, and insulation in the floor above had begun to deteriorate from excess humidity.

The family was concerned about the effects on air quality, especially with young children in the home, and wanted a long-term solution that wouldn’t involve repeated maintenance.

Our Solution

Direct Waterproofing proposed a full crawl space encapsulation system to separate the interior of the crawl space from exterior moisture, while also addressing existing dampness and drainage.

Work Completed:

• Moisture Removal: Pumped out residual standing water and dried the space using industrial dehumidifiers.
• Drainage Installation: Installed a perimeter drainage trench with a small sump pit to redirect water.
• Vapor Barrier System: Applied a thick, reinforced vapor barrier to the entire floor and lower walls, fully sealing off the space.
• Insulation Upgrade: Replaced deteriorated insulation and sealed gaps in the floor joists to improve energy efficiency.
• Dehumidifier Setup: Installed a crawl-space-rated dehumidifier to maintain dry conditions and prevent mold.

The Result

The encapsulation system transformed the crawl space into a clean, dry, and sealed environment. Odors disappeared within a week, indoor air felt noticeably fresher, and the family saw improvements in heating efficiency during colder nights. The project was completed in just three days.

Frequently Asked Questions

1. What is crawl space encapsulation?
Encapsulation involves sealing the entire crawl space with a vapor barrier and controlling moisture through drainage and ventilation or dehumidification. It protects against mold, structural decay, and poor indoor air quality.

2. Do all homes in Kitchener need crawl space encapsulation?
Not all homes, but if your crawl space is exposed to soil, uninsulated, or experiences dampness, encapsulation is a smart investment for comfort, health, and home value.

3. How long does encapsulation last?
With proper installation and materials, a crawl space encapsulation system can last 20+ years with minimal maintenance.

4. Will it affect my home’s heating and cooling costs?
Yes. Sealing the crawl space helps stabilize temperatures and reduce energy use by eliminating cold drafts and moisture.

5. Can you install a sump pump in a crawl space?
Absolutely. We often recommend a sump pit and pump if water intrusion is a concern. This adds another layer of protection.
